#10523: clang 3.4.2 (and greater) defines  BOOST_NO_CXX11_SMART_PTR

  <dan@…>                            |  Milestone:  To Be Determined
   Status:  new                      |    Version:  Boost 1.56.0
Component:  None                     |   Keywords:  clang
 Severity:  Showstopper              |  BOOST_NO_CXX11_SMART_PTR
-------------------------------------+-------------------------------------
 Due to the following code in boost/config/stdlib/libstdcpp3.hpp
 BOOST_NO_CXX11_SMART_PTR (among other things) is getting defined for clang
 3.4.2 built with gcc-4.8.2 on CentOS 7.  Apparently clang 3.4.2 defines
 __GNUC__ as 4 and __GNUC_MINOR__ as 2.

 The net effect is that no get_pointer is defined for std::shared_ptr and
 boost::binds break down.

 #if __GNUC__ < 4 || (__GNUC__ == 4 && __GNUC_MINOR__ < 4) ||
 !defined(__GXX_EXPERIMENTAL_CXX0X__)
 #  define BOOST_NO_CXX11_HDR_CONDITION_VARIABLE
 #  define BOOST_NO_CXX11_HDR_FORWARD_LIST
 #  define BOOST_NO_CXX11_HDR_INITIALIZER_LIST
 #  define BOOST_NO_CXX11_HDR_MUTEX
 #  define BOOST_NO_CXX11_HDR_RATIO
 #  define BOOST_NO_CXX11_HDR_SYSTEM_ERROR
 #  define BOOST_NO_CXX11_SMART_PTR
 #else
 #  define BOOST_HAS_TR1_COMPLEX_INVERSE_TRIG
 #  define BOOST_HAS_TR1_COMPLEX_OVERLOADS
 #endif
